WXXM ("The Mic 92.1" FM) is a radio station owned and operated by iHeartMedia and serves the Madison, Wisconsin metropolitan area. The station airs a progressive talk format, and is noted for its loyal listener and advertiser base, whose outpouring of support for the format reversed a planned change by station management to convert the station to all-sports radio in early 2007. The station is also simulcast in the Milwaukee area over an HD Radio subchannel of WKKV-FM (100.7-HD3). WXXM also airs the "Pride Radio" LGBT-oriented format on their HD2 subchannel (92.1-HD2).
Throughout much of the 1980s and 1990s, 92.1 was WMAD, which programmed alternative rock music. The station had decent ratings, though its lower-powered signal did not saturate the market like many of the other local FM stations. (The station's current signal strength is concentrated on Madison's North and East sides, as well as the station's city of license, Sun Prairie.)
The Weather Information Exchange Model (WXXM) is designed to enable the management and distribution of weather data in digital format (XML). WXXM version 2.0, set to be finalized in 2014, is based on Geography Markup Language (GML) and is one of the GML Application Schemas. It is being developed by the US Federal Aviation Administration (FAA) and the European Organisation for the Safety of Air Navigation (EUROCONTROL). WXXM is a member of a family of data models designed for use in aviation safety, notably Aeronautical Information Exchange Model (AIXM) and the Flight Information Exchange Model (FIXM).
As of 2014, WXXM is an extension of IWXXM, which represents the operationally exchanged meteorological information defined by the International Civil Aviation Organization (ICAO). WXXM uses a similar design approach to IWXXM, but can represent additional types of weather information not covered in IWXXM.
WXXM has two main components. The package as a whole is referred to as WXXM:
